Description

PROCEDE DE SUREMBALLAGE ET DISPOSITIF POUR LA MISE EN OEUVRE DUDIT PROCEDE OVERPACKING METHOD AND DEVICE FOR CARRYING OUT SAID METHOD
La présente invention se rapporte principalement à un procédé de suremballage et à un dispositif pour la mise en oeuvre dudit procédé.The present invention relates mainly to an overpacking method and to a device for implementing said method.
La palettisation des charges prend de plus en plus d'importance dans la mesure où elle permet de réduire les coûts de la manutention, du stockage et du transport des marchandises. L'intérêt de la palettisation ne subsiste que si la charge atteint son stade ultime, c'est-à-dire la dépalettisation dans l'état où elle se trouvait lors de la palettisation. L'on utilise habituellement un suremballage en film plastique pour assurer la cohésion, le maintien et/ou la protection des charges palettisées, alors que la cohésion entre la charge et la palette est assurée, pour une palette standardisée, par un retour de film sous le plancher inférieur de la palette. La palette ainsi protégée va être manipulée par des engins tels que des chariots élévateurs ou des transpalettes dont les fourches vont pénétrer dans les entrées de la palette en perforant, ou pire en déchirant, le retour de film plastique. Il en résulte un affaiblissement ou la destruction de la liaison entre la palette et la charge palettisée.Palletizing loads is becoming increasingly important as it reduces the costs of handling, storing and transporting goods. The interest of palletization only remains if the load reaches its final stage, that is to say depalletization in the state it was in during palletization. A plastic film overwrap is usually used to ensure cohesion, maintenance and / or protection of palletized loads, while cohesion between the load and the pallet is ensured, for a standardized pallet, by a film return under the lower floor of the pallet. The pallet thus protected will be handled by devices such as forklifts or pallet trucks whose forks will penetrate into the entrances of the pallet by perforating, or worse by tearing, the return of plastic film. This results in a weakening or destruction of the connection between the pallet and the palletized load.
De plus, l'accrochage du suremballage sur la palette peut être compromis par les frottements du retour du film sous le plancher inférieur de la palette sur le sol, les quais de déchargement ou les plateaux des camions. Des procédés connus d'accrochage de la charge palettisée sur la palette ne présentent pas ces inconvénients ; par exemple, l'on accroche le film sous le plateau supérieur de la palette, ou l'on accroche l'extrémité du suremballage dans des encoches ménagées sur les plots solidarisant les plateaux supérieurs et inférieurs de la palette. Toutefois ces procédés ne s'appliquent pas aux palettes standards constituant 90 % des palettes réutilisables en rotation dans le monde entier.In addition, the hanging of the overpack on the pallet can be compromised by the friction of the return of the film under the lower floor of the pallet on the ground, the unloading docks or the platforms of the trucks. Known methods for attaching the palletized load to the pallet do not have these drawbacks; for example, the film is hung under the upper plate of the pallet, or the end of the overwrap is hung in notches formed on the studs securing the upper and lower plates of the pallet. However, these methods do not apply to standard pallets constituting 90% of reusable pallets in rotation worldwide.
C'est par conséquent un but de la présente invention d'offrir un procédé et un dispositif de mise en place des moyens de solidarisation de suremballage avec la palette ne risquant pas d'être endommagés ou détruits par les fourches des engins de manutention. C'est également un but de la présente invention d'offrir un tel procédé et un tel dispositif susceptibles d'être mis en oeuvre avec des palettes standardisées. C'est aussi un but de la présente invention de réaliser des charges palettisées dont le suremballage ne risque pas d'être endommagé ou détruit par les frottements de la palette sur le sol, les quais de débarquement ou les plateaux des camions. C'est également un but de la présente invention d'offrir un tel procédé automatique ou facilement automatisable.It is therefore an object of the present invention to provide a method and a device for setting up means for securing the overpack with the pallet, not risking being damaged or destroyed by the forks of handling equipment. It is also an object of the present invention to offer such a method and such a device capable of being implemented with standardized pallets. It is also an object of the present invention to produce palletized loads, the overpackage of which is not liable to be damaged or destroyed by the friction of the pallet on the ground, the landing docks or the platforms of the trucks. It is also an object of the present invention to provide such an automatic or easily automated process.
C'est aussi un but de la présente invention d'offrir un tel procédé permettant la solidarisation du suremballage avec la palette pour un coût de revient faible. C'est également un but de la présente invention d'offrir un tel procédé mettant en oeuvre une faible quantité de films plastiques pour la solidarisation d'un suremballage sur une palette.It is also an object of the present invention to offer such a method allowing the overpacking to be secured to the pallet for a low cost price. It is also an object of the present invention to provide such a method using a small amount of plastic films for the attachment of an overpack on a pallet.
Ces buts sont atteints en fixant à la base d'une charge palettisée une bande d'accrochage, en plissant cette bande de façon à ménager des passages pour les fourches des engins de manutention et en solidarisant la bande d'accrochage avec un suremballage, notamment avec une housse rétractable. En variante, l'on solidarise directement avec la palette la partie inférieure d'un suremballage du type housse ou banderolage et l'on dégage des passages pour les fourches des engins de manutention en plissant la partie du suremballage obstruant les entrées de la palette.These aims are achieved by fixing a hooking strip at the base of a palletized load, by pleating this strip so as to provide passages for the forks of handling equipment and by securing the hanging strip with an overpack, in particular with a retractable cover. As a variant, the lower part of an overpack of the cover or wrapping type is joined directly to the pallet, and passages for the forks of handling equipment are released by pleating the part of the overpack obstructing the entrances to the pallet.
L'invention a principalement pour objet un procédé de suremballage d'une charge palettisée comportant une étape de dépose d'un ou de plusieurs films plastiques autour de la charge palettisée qui recouvrent la charge palettisée et obstruent les entrées de la palette, caractérisé en ce qu'il comporte une étape consistant à dégager dans le film obstruant les entrées de la palette des passages permanents pour des fourches des engins de manutention.The main object of the invention is a method of overpacking a palletized load comprising a step of depositing one or more plastic films around the palletized load which cover the palletized load and obstruct the entrances of the pallet, characterized in that that it comprises a step consisting of releasing permanent passages for the forks from handling machines in the film blocking the entrances to the pallet.

Sur la figure 1 , l'on peut voir une charge palettisée 1 de type connu comportant une palette 2 portant une charge 3 recouverte avec une housse 4 en film plastique rétracté lors d'une étape de chauffage. La housse 4 comporte des retours 5 sous le plancher inférieur 6 de la palette 2. Les retours 5 assurent au départ un bon maintien de la charge 3 et une bonne cohésion de la charge palettisée. Malheureusement, les frottements de la charge palettisée 1 sur le sol, les quais de chargement ou les plateaux des camions détruisent les retours 5, ce qui peut conduire à la dislocation de la charge palettisée 1. De plus, comme illustré sur la figure 2, lors des manutentions, les fourches 7 des chariots élévateurs ou des transpalettes, en pénétrant dans les entrées 8 de la palette, perforent ou pire déchirent le suremballage. Les déchirures 9 présentes sur les deux ou sur les quatre flancs de la palette 2 ne permettent plus au film plastique du suremballage de garantir la cohésion de la charge palettisée 1. Il peut en résulter une dislocation de la charge palettisée 1 avec des dommages aux colis de la charge 3.In Figure 1, we can see a palletized load 1 of known type comprising a pallet 2 carrying a load 3 covered with a cover 4 of plastic film shrunk during a heating step. The cover 4 includes returns 5 under the lower floor 6 of the pallet 2. The returns 5 ensure good hold of the load 3 at the start and good cohesion of the palletized load. Unfortunately, the friction of the palletized load 1 on the ground, the loading docks or the platforms of the trucks destroys the returns 5, which can lead to the dislocation of the palletized load 1. In addition, as illustrated in FIG. 2, during handling, the forks 7 of the forklifts or pallet trucks, entering the entries 8 of the pallet, perforate or worse tear the overpack. The tears 9 present on the two or on the four sides of the pallet 2 no longer allow the plastic film of the overpack to guarantee the cohesion of the palletized load 1. This can result in a dislocation of the palletized load 1 with damage to the packages of the load 3.
Sur la figure 3, l'on peut voir une charge palettisée 10 selon la présente invention comportant une bande d'accrochage 11 du suremballage 12 ménageant sur deux ou quatre côtés des passages 13 dans les entrées 8 de la palette 2. La bande d'accrochage 11 est solidarisée avec le suremballage 12, par exemple, par soudure ou par collage.In Figure 3, we can see a palletized load 10 according to the present invention comprising a fastening strip 11 of the overwrap 12 providing on two or four sides of the passages 13 in the inlets 8 of the pallet 2. The strip of attachment 11 is secured to the overpack 12, for example, by welding or by gluing.
Les passages 13 permettent la pénétration des fourches 7 dans les entrées de la palette sans perforation ni déchirure du suremballage 12 ni de la bande d'accrochage 11. La mise en oeuvre d'une bande d'accrochage 11 distincte du suremballage 12 laisse une grande liberté dans les choix des films plastiques à mettre en oeuvre pour ces deux éléments. L'on choisit, par exemple, pour le suremballage 12 une housse ou un banderolage adapté pour protéger et assurer la cohésion de la charge 3 et, pour la bande d'accrochage 11 , l'on choisit un film résistant à la traction et/ou aux frottements.The passages 13 allow the forks 7 to penetrate into the entries of the pallet without perforation or tearing of the overpack 12 or of the fastening strip 11. The use of a fastening strip 11 separate from the overpack 12 leaves a great deal of freedom in the choice of plastic films to be used for these two elements. One chooses, for example, for the overpack 12 a cover or a wrapping adapted to protect and ensure the cohesion of the load 3 and, for the fastening strip 11, one chooses a film resistant to traction and / or friction.
Sur la figure 4, l'on peut voir l'exemple préféré de réalisation d'un dispositif 14 de suremballage selon la présente invention.In Figure 4, we can see the preferred embodiment of an overpack device 14 according to the present invention.
Le dispositif 14 comporte un automate programmable 15 et un bâti 16 sur lequel est monté un cadre 17 assurant la sustentation d'un anneau 18 comprenant un dispositif 19 de distribution d'un film plastique formant la bande d'accrochage 11. L'on met avantageusement en oeuvre un film étirable mince, légèrement collant. Le dispositif 19 comporte, par exemple, une bobine 20 du film plastique étirable formant la bande d'accrochage 11 et deux rouleaux 21 , 22, avantageusement motorisés, assurant l'étirage du film. Des moyens moteurs non représentés assurent sur commande l'automate programmable 15, le déplacement du dispositif 19 de distribution du film sur l'anneau 18 ainsi que la translation verticale du cadre 17 permettant son effacement, avantageusement en hauteur, lors de l'amenée ou de l'évacuation d'une charge palettisée à suremballer. Le dispositif 14 selon l'invention comporte au niveau de la palette 2 des moyens 23 de fixation provisoire de l'extrémité du film formant la bande d'accrochage 11 du suremballage comportant, par exemple, une pince ainsi que des moyens 24 pour dégager la bande d'accrochage 11 au niveau des entrées 8 de la palette 2 en formant dans la bande 11 les passages 13 des fourches 7. Des moyens 24 comportent, par exemple, deux butées disposées sur deux côtés opposés, comme illustré, ou sur les quatre côtés de la palette 2.The device 14 comprises a programmable automaton 15 and a frame 16 on which is mounted a frame 17 ensuring the lifting of a ring 18 comprising a device 19 for distributing a plastic film forming the fastening strip 11. We put advantageously using a thin, slightly sticky stretch film. The device 19 comprises, for example, a reel 20 of the stretchable plastic film forming the fastening strip 11 and two rollers 21, 22, advantageously motorized, ensuring the stretching of the film. Motor means not shown ensure on command the programmable automaton 15, the movement of the device 19 for distributing the film on the ring 18 as well as the vertical translation of the frame 17 allowing its erasing, advantageously in height, during the feeding or evacuation of a palletized load to be overwrapped. The device 14 according to the invention comprises, at the level of the pallet 2, means 23 for temporarily fixing the end of the film forming the fastening strip 11 of the overwrap comprising, for example, a clamp as well as means 24 for releasing the fastening strip 11 at the entries 8 of the pallet 2 by forming in the strip 11 the passages 13 of the forks 7. Means 24 comprise, for example, two stops arranged on two opposite sides, as illustrated, or on the four sides of the pallet 2.
Comme l'on peut le voir sur la figure 6, chaque butée des moyens 24 comporte un élément d'appui 25 entraîné avantageusement vers le haut par un actionneur (non représenté) pour plisser les films et ménager les passages 13 ainsi qu'une soudeuse 26 pour souder les plis entre eux et former de façon permanente lesdits passages 13. Dans le cas de mise en oeuvre de butées sur les quatre côtés de la palette 2, certaines butées sont escamotables pour permettre l'amenée et/ou l'évacuation des palettes, par exemple à l'aide d'un convoyeur 27 à rouleaux motorisés 28. Dans l'exemple illustré, les moyens 24 pour dégager la bande d'accrochage 11 au niveau des entrées 8 de la palette 2 comportent uniquement quatre butées disposées sur les deux côtés opposés du convoyeur 27 qui s'escamotent uniquement pour se dégager de la bande d'accroché 11. Avantageusement, le dispositif 14 selon l'invention comporte des moyens d'élévation de la palette 2 pour permettre le passage de la bande d'accrochage 11 ou de la housse 12 sous le plancher inférieur 6 de la palette 2.As can be seen in FIG. 6, each stop of the means 24 comprises a support element 25 advantageously driven upwards by an actuator (not shown) for pleating the films and providing the passages 13 as well as a welder 26 to weld the folds together and permanently form said passages 13. In the case of implementation of stops on the four sides of the pallet 2, certain stops are retractable to allow the supply and / or evacuation of pallets, for example using a conveyor 27 with motorized rollers 28. In the example illustrated, the means 24 for releasing the fastening strip 11 at the entries 8 of the pallet 2 comprise only four stops arranged on the two opposite sides of the conveyor 27 which retract only to disengage from the fastening strip 11. Advantageously, the device 14 according to the invention comprises means for raising the pallet 2 to allow the passage of the a hanging strip 11 or the cover 12 under the lower floor 6 of the pallet 2.
Le dispositif 14 selon l'invention comporte avantageusement des moyens de dépose d'un suremballage 12 adapté à la charge palettisée. Dans l'exemple avantageux illustré, le dispositif 14 comporte des moyens 29 de dépose de housses rétractables comportant une bobine 30 d'une gaine en film rétractable, des moyens de coupure et de soudure de la partie supérieure de la housse (non représentée), des moyens de guidage 31 lors de la dépose de la housse sur la charge palettisée, par exemple un cadre, et des moyens de chauffage 32 pour assurer la rétraction de la housse. Les moyens de chauffage 32 comportent, par exemple, un four, un cadre à air chaud, un cadre à flamme directe, un cadre infra-rouge électrique ou un cadre infra¬ rouge à gaz.The device 14 according to the invention advantageously comprises means for depositing an overpack 12 adapted to the palletized load. In the advantageous example illustrated, the device 14 comprises means 29 for depositing retractable covers comprising a coil 30 of a sheath made of shrink film, means for cutting and welding the upper part of the cover (not shown), guide means 31 during removal of the cover on the palletized load, for example a frame, and heating means 32 to ensure the retraction of the cover. The heating means 32 comprise, for example, an oven, a hot air frame, a direct flame frame, an electric infrared frame or a gas infrared frame.
Il est bien entendu que la mise en oeuvre d'un dispositif de suremballage 29 et/ou des moyens de chauffage 32 séparés du dispositif 14 ne sort pas du cadre de la présente invention. De même, la mise en oeuvre d'un dispositif 19 de distribution du film formant la bande d'accrochage 11 fixe associé à des moyens pour faire tourner la charge palettisée 10 ne sort pas du cadre de la présente invention.It is understood that the implementation of an overpack device 29 and / or heating means 32 separate from the device 14 does not depart from the scope of the present invention. Likewise, the use of a device 19 for distributing the film forming the fixed fastening strip 11 associated with means for rotating the palletized load 10 does not depart from the scope of the present invention.
Nous allons maintenant expliquer, en référence aux figures 4 à 8, la mise en oeuvre du procédé selon la présente invention. L'extrémité du film formant la bande d'accrochage 11 est fixée manuellement ou par un manipulateur commandé par l'automate programmable 15 (non représenté) dans les moyens 23.We will now explain, with reference to FIGS. 4 to 8, the implementation of the method according to the present invention. The end of the film forming the fastening strip 11 is fixed manually or by a manipulator controlled by the programmable automaton 15 (not shown) in the means 23.
Comme illustré sur la figure 5, les moyens 19 de distribution du film formant la bande d'accrochage 11 effectuent au moins un tour complet déposant une bande étirée autour de la palette 2 et des butées des moyensAs illustrated in FIG. 5, the means 19 for distributing the film forming the fastening strip 11 carry out at least one complete revolution depositing a stretched strip around the pallet 2 and the stops of the means
24. Une fois la bande d'accrochage 11 formée, le film est coupé et la queue du film est soudée sur le ou les premier(s) tour(s).24. Once the fastening strip 11 has been formed, the film is cut and the tail of the film is welded on the first turn (s).
Comme illustré sur la figure 6, les éléments d'appui 25 plissent localement la bande d'accrochage 11 en dégageant les passages 13. Les soudeuses 26 soudent entre les plis et assurent le maintien des passagesAs illustrated in FIG. 6, the support elements 25 locally fold the fastening strip 11 by clearing the passages 13. The welders 26 weld between the folds and maintain the passages
13 après désengagement des butées des moyens 24.13 after disengagement of the stops of the means 24.
Comme illustré sur la figure 7, l'on dispose un suremballageAs illustrated in Figure 7, there is an overpack
12, par exemple une housse rétractable sur la charge palettisée. Le suremballage 12 est fixé sur la bande d'accrochage 11 , avantageusement par soudure provoquée par le chauffage nécessaire à la rétraction de la housse.12, for example a retractable cover on the palletized load. The overpack 12 is fixed to the fastening strip 11, advantageously by welding caused by the heating necessary for the shrinkage of the cover.
En variante, comme illustré sur la figure 8, le suremballage est soudé, par exemple, par un bras de soudure 33 ou collé lors d'une étape séparée du procédé selon la présente invention.Alternatively, as illustrated in FIG. 8, the overpack is welded, for example, by a welding arm 33 or glued during a separate step of the method according to the present invention.
Le dispositif et le procédé selon l'invention peuvent être adaptés à des palettes spéciales. Sur les figures 9 et 10, l'on peut voir deux exemples de réalisation du dispositif 19 particulièrement bien adaptés à des palettes 34 à plateau supérieur débordant 35. Le film formant la bande d'accrochage 11 est avantageusement déposé pré-étiré sur les bords du plateau débordant 35. Dans la variante de la figure 10, le dispositif 19 comporte un rouleau 36 de pré-étirage de faible largeur par rapport à la largeur du film, ce rouleau étant avantageusement motorisé par un moteur 37, et prenant appui sensiblement au milieu du film. L'on assure ainsi un étirage plus important dans le milieu de la laize au droit du plateau 35. Ce dispositif, pour une quantité et une qualité de films données, permet de mieux envelopper le plateau débordant 35 tout en minimisant les risques de déchirure du film. Une palette 10 suremballée par le procédé selon la présente invention comporte sur au moins un côté, de préférence sur deux côtés opposés ou sur les quatre côtés, des passages 13 donnant aux fourches 7 accès aux entrées 8 de la palette 2 sans détériorer le suremballage 12. De plus, le frottement de la charge palettisée 10 sur le sol, les quais de déchargement ou les plateaux de camions, ne détériore pas l'accrochage du suremballage sur la palette.The device and method according to the invention can be adapted to special pallets. In FIGS. 9 and 10, two examples of embodiment of the device 19 can be seen which are particularly suitable for pallets 34 with an overhanging upper plate 35. The film forming the fastening strip 11 is advantageously deposited pre-stretched on the edges. of the protruding plate 35. In the variant of FIG. 10, the device 19 comprises a pre-stretching roller 36 of small width compared to the width of the film, this roller being advantageously motorized by a motor 37, and bearing substantially at the middle of the movie. This ensures a greater stretch in the middle of the width in line with the plate 35. This device, for a given quantity and quality of films, makes it possible to better wrap the overflowing plate 35 while minimizing the risks of tearing of the movie. A pallet 10 overwrapped by the method according to the present invention comprises on at least one side, preferably on two opposite sides or on all four sides, passages 13 giving the forks 7 access to the inlets 8 of the pallet 2 without damaging the overpack 12 In addition, the friction of the palletized load 10 on the ground, the unloading docks or the truck trays, does not deteriorate the attachment of the overpack to the pallet.
Il est bien entendu que la mise en oeuvre d'autres types de suremballage comme des housses étirables ou d'un banderolage d'un film étirable, rétractable et/ou étiro-rétractable fixé sur une bande d'accrochage 11 elle-même étirable, rétractable et/ou étiro-rétractable ne sort pas du cadre de la présente invention.It is understood that the implementation of other types of overwrapping such as stretch covers or of a wrapping of a stretch, shrink and / or stretch-shrink film fixed on a fastening strip 11 which is itself stretch, retractable and / or stretch-retractable does not depart from the scope of the present invention.
De même, l'accrochage direct du suremballage sur la palette avec dégagement des entrées de la palette 2 ne sort pas du cadre de la présente invention.Likewise, the direct attachment of the overpack to the pallet with clearance from the entrances to the pallet 2 does not depart from the scope of the present invention.
La présente invention s'applique notamment au suremballage des charges palettisées.The present invention applies in particular to the overpacking of palletized loads.
La présente invention s'applique principalement au suremballage des charges palettisées sur une palette standard. The present invention mainly applies to the overpacking of palletized loads on a standard pallet.
